avformat/hls: reuse the open connection for contiguous byte-range segments
CMAF and other EXT-X-BYTERANGE playlists address consecutive segments as
contiguous byte ranges of a single resource. Each segment was fetched with
a separate bounded request, paying a request/response round-trip per
segment even though the connection was kept alive.

Keep the AVIOContext open across segments of the same resource and seek to
the next segment instead of reopening, for contiguous ranges the seek
targets the current position and issues no request in practice.

Non-contiguous, encrypted and non-seekable cases fall back to the
previous reopen behaviour.
